Cometic Buick Big Block V8 .045in MLS Cylinder Head Gasket - 4.400in Bore

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for Buick Big Block V8 engines and features a 4.400-inch bore with a compressed thickness of 0.045 inches. This gasket is designed to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound and resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments, varying load conditions, and different surface finishes. This makes it suitable for use with both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.

This gasket fits a range of Buick vehicles, including models like the Electra, Riviera, and LeSabre from the late 60s through the mid-70s. It's a well-built component that aims to provide maximum sealing performance for your engine rebuild.
